[0090]The manufacturing method of the mask 1 of the present disclosure includes the following steps:
[0091]The mask includes the outermost layer, the first intermediate layer, the second intermediate layer and the innermost layer; the outermost layer and the second intermediate layer are composed of copper-based zeolite fiber layers; the first intermediate layer is a hydrophobic fiber layer; the innermost layer is a hydrophilic fiber layer.
[0092]Among them, the first intermediate layer is composed of low-density and hydrophobic or water-resistant fibers. Typically, a low-density point-bonded non-woven fabric layer made of polyethylene terephthalate fiber and polyethylene subjected to pressure point bonding processing can be used. The pore size of the first intermediate layer is set at 40-60 μm.
[0093]The innermost layer is a layer of water-absorbing non-woven fabric.

[0121]The manufacturing method of the mask 2 of the present disclosure includes the following steps:
[0122]The mask includes the outermost layer, the first intermediate layer, the second intermediate layer and the innermost layer; the outermost layer and the second intermediate layer are composed of copper-based zeolite fiber layers; the first intermediate layer is a hydrophobic fiber layer; the innermost layer is a hydrophilic fiber layer.
[0123]Among them, the manufacturing methods of the copper-based zeolite fiber layer of the outermost layer and the second intermediate layer are as follows:
[0124](1) Preparing the zeolite precursor solution according to the following molar ratio of 8Na2O:Al2O3:9SiO2:180H2O. 60 cotton fiber were twisted and spun into fiber threads. The zeolite precursor solution and the fiber threads were mixed uniformly and heat treated at 110° C. for 36 h to obtain Y-type zeolite fiber threads. After soaking in a 5M copper sulfate solution for 3 times, each time f...
